Let's start with Pointy here. As you can see, his HP is respectable. Moving on to attack. It seems to skyrocket at the max, but quite low at minimum. His defense isn't all that but you might not want him to be walling. Look at that special attack! He's obviously meant for Special Sweeper! His Special Defense isn't all that bad, either. Speed is high, naturally. And that all comes to a rockin' 580 total.

Mister Firebird up next. He seems to have the same HP as Zapdos, nothing special here. Okay, we have an attack here we can easily work with, with a defense we don't want much but have to bear with. Special Attack of Moltres, as a fire type, is quite good, but the same as Zappy. Special Defense is nice but it could get KO'd with little difficulty. Speed is more on the average side. But it's good. Again, rounding up to 580.

Meet Frosty, the supposed leader of this trio. He likes having the same HP as his counterparts, Zapdos and Moltres. His attack is poor, but he only has about twelve physical moves so, that's not important. Wow. Apparently, this guy has the highest defense of the trio. But a low Special Attack. All in all, his power doesn't seem so impressive. But WOW, he is so born to be a Special Wall! Look at his Maximum 383 Special Defense. Could make up for the other average-like stats! So, Articuno is a not-bad choice for a Special Wall.
